Application filed. June 5, 1918. Serial No. 238,324.

To all whom it may concern:

Be it known that I, EMILE TINTANNI J, a citizen of the United States,residing at Camaguey, in the Province of Oamaguey and Republic of Cuba,have invented certain new and useful Improvements in Scribers, of whichthe following is a specification, reference being had to theaccompanying drawings.

This invention relates to certain improve ments in scribers and it is anobject of the invention to provide a device of this general characterhaving novel and improved means whereby the same may be employed toproduce a curved line of varying radius.

The invention also has for an object to provide an instrument of thisgeneral character including a main or supporting leg together with amarking implement yieldably supported by the leg or supporting memberwhereby said marking implement is movable relative to the supporting legor member so that the marking implement may readily follow a guidingedge.

Another object of the invention is to provide a novel and improvedinstrument of this general character which includes a supporting legormember yieldingly supporting a marking implement and wherein a guidemember coacts with the marking implement for controlling the workingmovement of the implement together with means for relatively adjustingthe guiding member and the marking implement.

Furthermore, it is an object of the invention to provide a novel andimproved instrument of this general character including a supporting legor member having yieldably connected thereto a sleeve with which amarking implement is supported and wherein said marking implement iscapable of lateral and longitudinal movement independently of the sleevetogether with means coacting with the implement for constantly urgingthe same in a direction away from the work.

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved soriberwhereby certaln important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein:

Figure 1 is a view in side elevation of a scriber constructed inaccordance with an embodiment of my invention;

Fig. 2 is a fragmentary view partly in longitudinal section and partlyin elevation illustrating certain features of the invention as hereindisclosed;

Fig. 3 is a sectional view taken substantially on the line 3-3 of Fig.1;

Fig. l is an enlarged fragmentary sectional view illustrating the meansfor adjusting the marking implement relative to the guide member;

Fig. 5 is a fragmentary view in elevation with a part in section of themarking implement and the adjusting member coacting therewith;

Fig. 6 is a fragmentary view in elevation of the working end portion ofthe guide member; and

Fig. 7 is a fragmentary view in plan of a guide with which mv improvedscriber may be employed.

As disclosed in the accompanying drawings L denotes a supporting leg ormember having engaged with the working end thereof in a conventionalmanner the needle N. The opposite end portion of the leg or member L isfluted or otherwise roughened as at 1 to facilitate the manipulation ofthe instrument. S denotes a sleeve of predetermined dimensions arrangedat one side of the leg or member L and the inner or upper end portion ofsaid sleeve is connected with the upper end portion of the leg or memberL through the medium of the flat spring 2 possessing the greatest degreeof flexibility at the portion a immediately adjacent the connectionbetween the spring 2 and the leg L. The spring 2 serves to constantlyurge the sleeve S in a direction away from the supporting leg or memberL. The lower or outer end portion of the sleeve S has pivotally engagedtherewith as at 3 the end portionof the flexible member or spring 4:which is disposed through a suitable opening 5 in the leg or member Ladjacent the needle N and coacting with the spring 4 is the screw 6 inthreaded engagement with the leg or member L and adapted to frictionallyengage the spring 4. The screw 6 and the spring 4 coact to prevent anabrupt upward or jumping movement of the sleeve S and more particularlythe marking implement (to be hereinafter more particularly referred to)when the marking implement is free from the work.

As herein illustrated the marking implement M comprises a bow pen of aconventional type detachably engaged Within a head or socket 8 providedat the lower end portion of the cylindrical stem 9. It is to beunderstood that I do not wish to limit myself to any particular type ofmarking implement as the same may be a pencil or other marking orwriting medium.

The stem 9 is of a length in excess of the .length of the sleeve S andis slidably disposed through the sleeve and the shoulder 10 afforded bythe head or socket 8 normally contacts with the lower or outer endportion of the sleeve S.

Engaged with the upper or outer end portion of the stem 9 is a headedmember 11 and secured to the peripheral portion of the head of saidmember is an extremity of a coil spring 12. The spring 12 encircles theportion of the stem above the sleeve S and has its opposite end portionanchored to the inner or upper end portion of said sleeve. This springconstantly urges the stem 9 inwardly or upwardly yet permits sufiicientrotation of the stem Within the sleeve to meet the requirements ofpractice.

T denotes a trace or guide member formed of resilient material andhaving one end suitably anchored to the outer face of the head or socket8. In the present embodiment of my invention an end portion of the traceor guide member T is inserted within a supplemental socket or recess inthe head 8 and engaging said end portion of the trace or guide member Tis a clamping screw 8 or the like in threaded engagement with the head8. The member adjacent the socket is bent upwardly and downwardly toafford a loop to increase the spring action of this 1 member and thefree end portion of the member is substantially straight and ispositioned in close proximity to the outer face of the marking implementM. The free extremity of the member T normally extends beyond theworking end of the implement M so that in setting the instrument themarking implement is out of contact with the work. l/Vhen it is desiredto produce or inscribe a line it is only necessary for the operator topress downwardly upon the stem 9 and which pressure may be partlyobtained by one of the digits ofthe hand engaged with the supporting legor member L. As soon as the stem 9 is relieved of this pressure thespring 12 immediately returns the implement M to its normal position.The free end portion of the member T is provided with the lateralextension 15 which is adapted to afford an increased surface for contactwith the working edge of the guide G. The guide Gr is preferably of thetype particularly described and illustrated in my 00- pendingapplication executed on even date herewith Serial No. 238,325. Theworking edge of said guide as herein illustrated is a wall produced byan opening in the plate preferably of transparent xylonite or othertransparent material.

In use the needle N is fixed at approximately the center of the opening0 in the guide G with the lower or working end of the member T incontact with the edge de fining said opening. Pressure is then appliedto the stem 9 to bring the marking im-' plement M in contact with thepaper. Upon turning movement of the leg or member L the implement M willproduce upon the paper or other surface worked upon a line concentric tothe edge of the opening 0. In view of this it will be at once understoodthat my improved scriber is of especial ad vantage in the production ofa line arranged on a curve of varying radius such as is required in theforming of script lettering employed in connection with geometricaldesign. The production of a line of this character is facilitated by therelative movement between the sleeve S and the leg or member L and thelongitudinal and rotatable movement of the stem 9 relative to the sleeveS.

The upper or inner end portion of the straight portion 1 1 of the memberT has secured to the front face thereof a block 16 and which block ispreferably held .in position by solder, although I do not Wish to beunderstood as limiting myself in this respect. Threaded through theblock 16 is a headed shank 17 and the free end portion 18 of said shank17 has its periphery smooth as particularly illustrated in Fig. 1, andtheportion 18 is disposed through the slot or slots 19 produced in themarking implement M. Threaded upon the shank 17 adjacent the portion 18thereof is a nut or head 20 which contacts with the marking imple ment Mso that upon endwise movement of the shank 17 the implement M may bespaced relative to the part 14 of the member D as the occasions ofpractice may require in or der to produce lines concentric to theguiding edge as afforded by the opening Ointhe guide G but of differentaxes.

It is of importance that the part 14 of the guide member T besubstantially rigid and it is also of importance to provide the lowerportion of the part 14. with a small bearing member or block 21 whichassures at all times a slight separation between the part 14 of themember T and the marking implement M.

From the foregoing description it is generally,

thought to be obvious that a scriber constructed in accordance with myinvention is particularly well adapted for use by reason of theconvenience and facility with which it may be assembled and operated andit will also be obvious that my invention is susceptible of some changeand modification without departing from the principles and spiritthereof and for this reason I do not wish to be understood as limitingmyself to the precise arrangement and formation of the several partsherein shown in carrying out my invention in practice except ashereinafter claimed.

I claim:

1. A scriber consisting of a supporting leg, a marking implement, aresilient member connecting the marking implement and the leg, saidresilient member urging the marking implement in a direction away fromthe leg, a. flexible member operatively engaged with the markingimplement, and means carried by the leg for frictionally engaging theflexible member.
